Description
The XL6009 DC-DC Boost Converter Module is a high-efficiency, compact step-up (boost) power supply module capable of delivering up to 4A output current, making it ideal for high-power, space-constrained applications. Powered by the XL6009 switching IC, this module offers significantly higher efficiency and smaller size compared to older LM2577-based regulators.
Operating at a switching frequency of 400kHz, the module supports both regulated and unregulated DC inputs (3V–32V) and provides an adjustable output voltage in the range of 5V to 35V, making it perfect for audio projects, battery-powered devices, and custom power supplies.
With onboard potentiometer-based output control, short-circuit protection, and up to 94% efficiency, this boost converter is a reliable choice for engineers, students, and DIY enthusiasts.

Frequently Asked Questions (FAQ)
Q1: Can I boost 5V to 12V with this module?
✅ Yes! As long as the input voltage is at least 1.5V lower than the output, the module can step it up.
Q2: What’s the maximum output power?
⚠️ Theoretical output is 4A at up to 35V (140W), but practical use should be limited to <15W without heatsink, and <30W with proper cooling.
Q3: Does this module support synchronous rectification?
No. It uses non-synchronous rectification, but remains efficient up to 94%.
Q4: Can I use this for Li-ion battery charging?
⚠️ Only if properly regulated. For battery charging, a constant current/voltage charger is better suited.
Q5: What’s the difference between XL6009 and LM2577 modules?
✅ The XL6009 offers better efficiency, higher frequency (smaller size), and improved voltage stability.
